I2S/PCM Stereo DAC + Multiple Analog Inputs, Headphone, and Mono Class-D Speaker Amplifier General DescriptionThe ALC5627 is a highly-integrated I2S/PCM interface audio DAC with multiple input/output ports, and is designed for multimedia handheld devices. It provides a Stereo Hi-Fi DAC for playback via the I2S/PCM interface.To reduce component count, the ALC5627 can connect to:LINEIN_L/R stereo Single-Ended analog inputs that can be configured to Differential analog inputAUXIN_L/R stereo Single-Ended analog inputs that can be configured to Differential analog inputSingle-Ended stereo HeadphoneMONO Bridge-Tied Load (BTL) SpeakerMultiple analog input and output pins are provided for seamless integration with analog connected wireless communication devices. Differential input/output connections efficiently reduce noise interference, providing better sound quality. Class-D amplifiers can be directly connected to an up to 2.4 Watt Mono Speaker, removing the need for an additional amplifier, further cutting both cost and required board area.The ALC5627 AVDD operates at supply voltages from 2.3V to 3.6V. DCVDD and DBVDD operate from 1.8 to 3.6V, and SPKVDD operates from 2.3 to 5V. To extend battery life, each section of the ALC5627 can be powered down individually under software control. Leakage current in maximum power saving state is less than 10µA.The ALC5627 is available in a 5x5mm ‘Green’ QFN-32 package, making it ideal for use in handheld portable systems.FeaturesDigital-to-Analog Converter with 100dB SNR, and –86dB THD+N at 3.3VTwo analog stereo single-ended or one stereo differential input, LINEIN_L/R and AUXIN_L/RBTL (Bridge-Tied Load) Class-D Speaker output with on-chip 2.4W speaker driver (SPKVDD=5V, 4W load)Supports playback soft-mute, digital volume, digital AVCStereo headphone output with on-chip 45mW headphone driver (AVDD=3.3V, 16W load)Supports pop noise suppression with external capacitorSpeaker amplifier power supplies from 2.3V to 5VDigital power supplies from 1.8V to 3.6VAnalog power and headphone power supplied from 2.3V to 3.6VPower management and enhanced power savingInternal PLL can receive wide range of clock inputSupports sampling rate 8KHz ~ 192KHzSupports I2C control interfaceSupports three programmable data interfacesI2S, left justified, or DSP16/20/24 bits word lengthMaster or Slave clock mode32-pin QFN 5x5mm package for small footprintApplicationsPortable media playerMP3 playerBluetooth A2DP (Advanced Audio Distribution Profile) headsetsPortable Navigation Device (PND)
